Patent number: 7705159Abstract: The invention provides a high-yield process for the preparation of letrozole having a high purity, without the need for removal of the 4-[1-(1,3,4-triazolyl)methyl]benzonitrile impurity at the intermediate stage. The invention also provides a process for the synthesis of letrozole in which formation of the impurity 4-[1-(1,3,4-triazolyl)methyl]benzonitrile during the first stage is minimized. In the process, a 4-(halomethyl)benzonitrile is reacted with a salt of 1H-1,2,4-triazole, reducing the formation of the impurity. Preferably, the preparation is conducted as a one-pot process.Type: GrantFiled: July 6, 2006Date of Patent: April 27, 2010Assignee: Sicor, Inc.Inventors: Peter Lindsay MacDonald, Ettore Bigatti, Pierluigi Rossetto, Zvi Harel

Patent number: 7501455Abstract: The invention is related to water-soluble products and pharmaceutical formulations in solid or liquid form mainly for parenteral use. They consist of or comprise a therapeutically active substance (having low aqueous solubility and a substantial binding affinity to plasma proteins) and a plasma protein fraction in controlled aggregation state, whereby the said active substance and the said protein fraction are bound to each other by way of non-covalent bonds. It also covers processes for the preparation of the product and pharmaceutical formulation by dissolving the water-insoluble active substance in a water-miscible, pharmaceutically acceptable solvent, combining said solution with the aqueous solution of a plasma protein fraction in controlled aggregation state whereby a true solution is obtained containing the said active substance and the said protein fraction bound together by way of non-covalent bonds.Type: GrantFiled: March 17, 2004Date of Patent: March 10, 2009Assignee: Sicor, Inc.Inventors: Lajos Hegedus, Krisztina Krempels, Krisztina Paal, Gabor Petho
